IMPROVED GAS OR. OTHER RETORT.

Specification forming part of Letters Patent No. 45,908, dated January17, 1865; antedated January 6, 1865.

To all whom it may concern.-

Be it known that 1, JOHN UHILOOTT, of 70 Fulton street, in the city ofBrooklyn, county of Kings, and State of New York, have invented a newand useful Improvement in Gas and other Retorts; and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming part of thisspecification, in which- Figure 1 is a front view of a retort with myimprovement. Fig. 2 is a central longitudinal vertical section of thesame. 7 Fig. 3 is a transverse section of the same in the plane indicated by the line 00 an in Figs. 2 and 4. Fig. 4 is a horizontal sectionof the retort-casingbelow the retort.

Similar letters of reference indicate corresponding parts in the severalfigures.

The object of this invention is to heat every portion of the retort andreduce the consumption of fuel; and to this end it consists insurrounding the bottom, sides, and top of a retort with a jacket orcasing, between the in terior of which and the exterior of the retort acontinuous system of fines is formed by means of longitudinal partitionshaving openin gs at opposite ends alternately, so that the flame andheated gaseous products of combustion from the furnace may circulateback and forth several times along and once all around the retort beforeescaping to the chimney.

It also consists in a certain construction of the cash) g andpartitions, whereby provision is made for cleaning the fines.

To enable others skilled in the art to make and use my invention, 1 willproceed to describe its construction and operation.

A is the retort, made of fire-clay or cast-iron of the usual D shape(represented in Fig. 3) or of other suitable form, and having a movablehead, 13, at the front end.

0 is the jacket or casing, of the samematerial as the retort, and havinga transverse sectional form corresponding with that of the retort, butof considerably larger area, so as to provide a sufficient space betweenits interiorand the exterior of the retort, all around, to'form thefines E E. This jacket or casing is somewhat shorter than the retort, sothat the retort, fitting close against its closed rear end, may protrudesome distance from its front end, as shown in Fig. 2. The open front endof said casing is constructed with an external projecting flange, a, atits top and sides, to which to attach movable head-plates F and G byscrew-bolts b b, for the purpose of closing the front of the fine-spacebetween it and the retort, the said plates fitting closely around theexterior of the retort.

0 c are the longitudinal partitions between the retort and the jacket orcasing, which divide the intermediate space into fines E E, arranged atequal distances apart all around the retort and jacket, those which arebetween the fiat bottom and sides of the retort and jacket being atright angles thereto, and those between the arched tops thereof beingradial thereto. These partitions are formed upon the interior of thejacket and fit closely to the exterior of the retort, and they extendthe whole length of the retort and jacket, except that in each there isan opening, 11, the said opening in one being at the front end, and thatin the next on either side being at the other end, as shown in Figs. 2and 4.

The retort is supported within the jacket G by resting on the upperedges of the partitions c 0. p

z is the inlet-opening in the jacket, leading to the system of flues EE. This opening is situated in the bottom, at the front end and close tothe left-hand side of the retort and jacket, as shown in Figs. 3 and 4.

e is the exit-opening in the lowest flue on the lefthand side of theretort, next to that fiue in which is the inlet-opening t, as shown inFig.3.

The openings (1 in the partitions c c are respcctively so arrangedrelatively to the inlet and exit openings 'i and c that the flame andheated gaseous products of combustion from r the furnace entering oneflue at the inlet-opening may pass in a rearward direction along thatflue, return in a forward direction by the next one at the right hand,rep-ass in a rearward direction along the next, and so on through allthe fines under the bottom of the retort, thence back and forth throughthose on the right-hand side, afterward through those on the top, andfinally through those on the left-hand side, thus making the completecircuit of the retort and escaping by the exitopening.

In order to provide for the removal of the retort from the jacket andintroducing a new retort or jacket,the jacket is divided horizontallyand longitudinally into two parts, which are fitted together withtongues and grooves, as shown at g g, in Fig. 8.

The cleaning out of the fines may be effected by taking off theremovable head-plates F and G, the junction of which corresponds withthe junction of the upper and lower portions of the jacket. To obviatethe necessity of taking 01f these heads, there may be provided therein aseries of openings-one opposite to each fluethe said openings beingfitted with removable bonnet-plates h h, as shown in Fig. 1.

Any convenient number of retorts, each fitted with a flue-jacket, 0, maybe arranged in one bench, provided the inlet-openings c of theseveraljackets are properly arranged with respect to the fireplace orfurnace, and the exit-openings e are properly arranged with respect tothe chimney, that all the flames and heated products of combustion maypass through the jackets on their way to the chimney the flame andgaseous products being properly divided between the several jackets.

Each jacketmay be provided with more than one inlet-opening and morethan one outletopening, if the openings 01 in the partitions c c areproperly arranged. The inlet and outlet openings may be reversed-that isto say, 0 may be the inletand i the outlet.

What I claim as my invention and desire to secure by Letters Patent, is

1. Surrounding the bottom, sides, and top of a gas or other retort witha jacket or casing, 0, between which and the retort a continuous systemof fiues, E E, is formed by means of longitudinal partitions havingopenings at opposite ends alternately, whereby the flame is caused tocirculate back and forth several times along and once all around theretort, substantially as and for the purpose herein specified.

2. The jacket or casing 0, divided longitudinally into two parts, andhaving the flue'partitions attached to its interior, so as to bedetachable from the retort, substantially as and for the purpose hereinspecified.
